Laparoscopic Management of Ureteropelvic Junction Obstruction by Division of Anterior Crossing Vein and Cephalad Relocation of Anterior Crossing Artery

Abstract

Select cases of UPJ obstruction associated with anterior crossing vessels seem to be amenable to laparoscopic management by division of the crossing vein and cephalad relocation of the crossing artery. Laparoscopy as a minimally invasive approach may offer a better opportunity to evaluate the role of anterior crossing vessels in UPJ obstruction.
